## FAQ
Q: Was aviation security or flight safety compromised in the MAG breach?
A: No. MAG and UK media confirm passenger safety and aviation security were not affected. The incident targeted commercial customer systems (WiFi sign-ups, parking, lounge and Fast Track bookings), not airside operational or safety systems.

Q: What personal data was stolen from UK airport customers?
A: Email addresses (mostly from in-terminal WiFi registration), plus phone numbers, vehicle registration numbers and postcodes for customers who booked car parking, lounge access or Fast Track services. No payment card or bank details were held in the accessed system.

Q: How did hackers access Manchester Airport customer data?
A: MAG has confirmed an unauthorised third party obtained data from commercial booking and WiFi systems but has not published the technical entry point. Industry pattern for similar extortion attacks includes compromised credentials, unpatched internet-facing applications, or supplier access paths into shared customer databases.

Q: What should affected airport passengers do now?
A: Watch for phishing emails, texts and calls referencing parking, WiFi or MAG bookings. Do not click unexpected links or open attachments. MAG states it will never ask for payment details or passwords by unsolicited message. Report suspicious contact to Action Fraud and follow ICO breach guidance.

Q: How can airlines and airport operators reduce passenger data risk?
A: Segment commercial systems from operational aviation networks, minimise what WiFi and parking flows store, shorten retention, tokenise where possible, and prove eligibility with signed outcomes instead of copying identity attributes into secondary databases.
